MC14518B 双路 BCD 计数器和 MC14520B 双路二进制计数器采用一个单片结构,使用 MOS P 沟道和 N 沟道增强型器件进行构造。每个器件都由两个相同、独立、内部同步的 4 级计数器组成。计数器级是 D 型触发器,具有可互换的时钟和启用线路,用于在级联多个级时根据需要在正向或负向转换上递增。每个计数器都可以通过在重置线路上应用高电平来清除。此外,MC14518B 将在两个时钟周期内计算出所有未定义的状态。这些互补 MOS 正数计数器主要用于需要低功耗和/或高抗扰性的多级同步或纹波计数应用。

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
